Abstract

A method and system for destroying information stored on a data storage device located onboard a vehicle in order to prevent unfriendly forces from obtaining the information is described. The method and system are initiated when the operator of the vehicle activates a triggering mechanism. The information may be destroyed by physically damaging the data storage device on which the information is stored or by releasing a software virus into the device on which the sensitive information is stored. A software virus may also be transmitted to a computer of an unfriendly force attempting to access the sensitive information.

Claims

1. A method comprising:

receiving, by an initiation device, a signal created by a triggering mechanism upon activation of the triggering mechanism by an operator of a vehicle, wherein the vehicle comprises the initiation device, the triggering mechanism, a first data storage device storing sensitive information, and a second data storage device storing confidential information, and wherein the sensitive information and the confidential information were designated prior to deploying the vehicle; and

in response to receiving, by the initiation device, the signal created by the triggering mechanism, controlling a destruct device to destroy, using at least one of physical impact by a mechanical device, a software virus, a chemical, a chemical explosive, or a magnet, the sensitive information while leaving the second data storage device storing the confidential information intact.

2. The method of claim 1, wherein the vehicle is a plane, wherein the operator is a pilot, and wherein the triggering mechanism is activated by activating an ejector seat on the plane.

3. The method of claim 1, wherein destroying the sensitive information includes releasing a software virus into the first data storage device.

4. The method of claim 1, wherein destroying the sensitive information includes using chemical explosives.

5. The method of claim 1, wherein destroying the sensitive information includes imparting physical damage to the data storage device via impact.

6. The method of claim 1, wherein destroying the sensitive information includes passing a magnet over the data storage device.

7. The method of claim 1, further comprising:

detecting, by a computer onboard the vehicle, unfriendly attempts to access the confidential information stored on the second data storage device; and

destroying, by the computer, the confidential information in response to detecting unfriendly attempts to access the confidential information.

8. The method of claim 7, wherein destroying the confidential information includes transmitting, by the computer onboard the vehicle, a software virus to a computer attempting to access the confidential information.

9. The method of claim 1, wherein the sensitive information comprises information that is more sensitive than the confidential information.

10. A method comprising:

prior to deploying a vehicle, designating sensitive information to be destroyed upon activation of a triggering mechanism;

prior to deploying the vehicle, designating confidential information to be destroyed upon detection of unfriendly attempts to access the confidential information;

storing the sensitive information on a first data storage device located onboard the vehicle;

storing the confidential information on a second storage device located onboard the vehicle;

receiving, by an initiation device, a signal from the triggering mechanism upon activation of the triggering mechanism by the operator;

controlling, by the initiation device, in response to the signal from the triggering mechanism, a destruct device to destroy the sensitive information using a destruct device located near the first data storage device while leaving the confidential information intact;

detecting, by a computing device, unfriendly attempts to access the confidential information stored on the second data storage device; and

destroying, by the computing device, the confidential information in response to detecting unfriendly attempts to access the confidential information.

11. The method of claim 10, further comprising removing an anti-tamper shield adjacent to the triggering mechanism before activating the triggering mechanism.

12. The method of claim 10, wherein destroying the sensitive information includes destroying the sensitive information using at least one of releasing a software virus into the first data storage device, using chemical explosives, using chemicals, using a magnet, or imparting physical damage to the first data storage device.

13. The method of claim 10, wherein destroying the confidential information includes releasing a software virus into the second data storage device, wherein the software virus destroys the confidential information.

14. The method of claim 10, further comprising transmitting a software virus to a computer attempting to access the second data storage device.

15. The method of claim 10, wherein the sensitive information comprises information that is more sensitive than the confidential information.

16. A system

a first data storage device storing sensitive information, wherein the first data storage device is located in a vehicle;

a second data storage device located in the vehicle, wherein the second data storage device stores confidential information;

a triggering mechanism located on the vehicle;

an initiation device coupled to the triggering mechanism; and

a destruct device located in the vehicle, wherein the destruct device is selected from the group consisting of a chemical explosive, a chemical, a magnet, a computer virus, and a mechanical device that physically damages the first data storage device, wherein the initiation device activates the destruct device when the triggering mechanism is activated, and wherein the destruct device, when activated, is configured to destroy information stored on the first data storage device while leaving intact the second data storage device.

17. The system of claim 16, wherein the triggering mechanism comprises a trigger that initiates an ejector seat system on an aircraft.

18. The system of claim 16, further comprising an anti-tamper shield that fits over the triggering mechanism.

19. The system of claim 16, wherein the sensitive information comprises information that is more sensitive than the confidential information.
